Chapter 20: Event Triggers

The controller does a lot of things totally under the control of the built-in firmware which you as

the user can't change, such as turning on a PTT when a receiver goes active and hanging up the

phone when it times out. Other things are done by calling automatic macros (see Chapter 8), such

as sending ID's and courtesy beeps. Although you can't control when the automatic macros get

called, you can control what they do. Event triggers give you even more flexibility. They allow

you to execute any of the built in commands or any of the macros whenever certain things happen.

All you have to do is tell the controller what command you want to do when each event occurs

with command 157. If you only want it to happen some of the time, you can just disable the event

trigger with command 159. If you tell the event trigger to execute a macro, you may need to

program the macro to do something (see Chapter 8). You should keep track of what command

you assign each event trigger to execute, as you may need to know later.

If you want to execute more than one command from an event trigger, make the event trigger call a

macro, then program the macro to execute each of the commands in turn. That way the event

trigger calls only a single macro and the macro takes care of calling multiple other commands.
